Meanwhile, Pratt showed off yet another string to his bow when asked about his musical tastes.

'I remember when Eminem [and Dr Dre] first came out with his album 2001. Me and my friend lived in a van in Maui and we listened to that and smoked weed every day,' he revealed. 'I know every word to that album.'

When challenged to prove his knowledge of the record, Pratt launched into an impressive rendition of the Dr Dre Feat. Eminem track
Forgot About Dre.

Career rise: Pratt will also star in the Jurassic Park sequel as well as being linked to a new Knight Rider project

The DJ was left speechless as the actor perfectly rapped at least 35 lines of the song without missing a beat from the track.

Pratt also discussed his role in Jurassic Park sequel Jurassic World along but dismissed as 'rumours' Internet reports he would be appearing in a new Knight Rider project, adding: 'The first I heard about it was something online honestly.'

It has been a successful few months for the Parks & Recreation actor with Marvel film Guardians Of The Galaxy getting rave reviews from critics who also widely hailed his performance as Peter Quill.

'Grateful!' Pratt posted his message on Saturday night and urged fans to watch the credits of the film to recognise the hard work of the cast and crew

'Thank you everyone watching #GuardiansOfTheGalaxy this weekend!' he wrote. 'We're all so happy that people are loving it.'

The cosmic romp, which also stars Zoe Saldana, Bradley Cooper, Vin Diesel and Dave Bautista, didn't only achieve great numbers at home, but also proved a smash across the world.

The action smash was originally
considered a risky proposition for Marvel and the film's distributor
Disney, because it features more obscure characters from the Marvel
universe and is set almost entirely in outer space.

Despite
any apprehension, Marvel was betting on Guardians to be a blockbuster,
with the studio announcing at Comic-Con in San Diego last month that a
sequel is already set for release in 2017.
